will to sell Mobius Interlude event Called Apocalypse.
so players register , everyone is on same team, they are defending Monolith from zombies to reach it, there is 3 waves of zombies, players have to kill 100 zombies on each wave to get to next wave (you can change number to any desired number), my view was to have diff powers to each wave, so you can modify zombies as well, after clearing all 3 waves, final boss spawns, if players beat the boss , collected coins on this particular event will double up (players might have coins from previous event but we track only coins collected from current event) and shop spawns, lose condition is like that if 20 zombies (or any number you like) reaches monolith, event is lost or if final boss reaches it. also people love skins so i have used existing transmog to give classes by armor type special skins (when event ends, everything being cleaned up).
i can help to set up client side things too if necessary .
if you want to test it, write me in private i will send you download link to server to see it.
Price 150$ and possible i can do some addons based on what you want to add
